CVE-2023-35349: 
vulnerability analysis and mitigation

Microsoft Message Queuing (MSMQ) Remote Code Execution Vulnerability (CVE-2023-35349) was disclosed on October 10, 2023. This critical vulnerability affects multiple versions of Microsoft Windows and Windows Server systems. The vulnerability has a CVSS base score of 9.8 (Critical), indicating its severe nature (NVD, Rapid7).

The vulnerability exists in the Microsoft Message Queuing (MSMQ) service and could allow an unauthenticated remote attacker to execute code on affected systems. The vulnerability has been assigned a CVSS vector of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating network accessibility, low attack complexity, and no required privileges or user interaction (NVD).

If successfully exploited, this vulnerability could allow an attacker to execute remote code on the target system with the Windows message queuing service enabled. The critical CVSS score of 9.8 indicates potential for complete compromise of system confidentiality, integrity, and availability (Arctic Wolf).

Primary mitigation involves applying the security updates provided by Microsoft for all affected systems. If patching is not immediately possible, organizations can disable the Message Queuing (MSMQ) service if not required in their environment. Additionally, blocking inbound connections to TCP port 1801 from suspicious sources can help prevent exploitation (Arctic Wolf).
